Hi from me. My (more recent) experience is similar but not identical. I
install sage from the ppa and I am having problems. Sage loads and seems to
be working, but:
┌────────────────────────────────────────────────────────────────────┐
│ SageMath version 7.3, Release Date: 2016-08-04 │
│ Type "notebook()" for the browser-based notebook interface. │
│ Type "help()" for help. │
└────────────────────────────────────────────────────────────────────┘
